摘要

高压SF

开关设备运行中的放电故障（火花放电、电弧、局部放电等）诱导SF

分解为低氟硫化物

放电温度降低带来的SF

复合过程仍可保证设备具有良好的绝缘和灭弧能力。然而

当低氟硫化物与设备内无法避免的水蒸气和氧气杂质发生反应时

产生的腐蚀性产物会对设备的正常运行带来威胁

从而为利用SF

特征分解产物进行故障诊断提供依据。因此

文中利用气相色谱仪诊断技术对火花放电下SF

特征分解产物SOF

和SO

的演化特性进行研究

结果表明产物的摩尔分数随水蒸气和氧气体积分数的增加而升高

火花放电能量的提升也对分解产物的生成具有促进作用。文中工作可以为高压开关设备故障诊断和运行状态在线监测奠定理论基础。

Abstract

Discharge faults（such as spark

arc and partial discharge） in high voltage SF

switchgear will induce SF

decomposition into low fluorine sulfides.However

the recombination of SF

molecules caused by the decreasing discharge temperature can still guarantee good insulation and arc-quenching performance of high voltage SF

switchgear.When the low fluorine sulfides react with the unavoidable trace moisture and oxygen impurities

the generated corrosive products will threaten normal operation of the high voltage SF

switchgear.Th

erefore

it is possible to make use of the characteristic SF

decomposition products to detect discharge faults.This study employs gas chromatograph to investigate the evolution of characteristic SF

decomposition products

like SOF

and SO

under spark discharge.The results show that the molar fractions of these products increase with the contents of moisture and oxygen

and the increase in the spark discharge energy also makes contribution to the generation of these products.This work may provide theoretical basis for fault diagnosis and condition online-monitoring of high voltage SF

switchgear.
